Since the onset of the pandemic, there's been a discussion about whether the COVID-19 vaccines can be considered vegan. While most vaccines avoid animal-derived ingredients, several vaccines including Pfizer have been tested on animals during the initial developmental phases. Now, Canadians can know for sure that their vaccine is fully plant-based. This week, the world’s first plant-based COVID-19 vaccine – the COVIDENZ – just received regulatory approval for public use across Canada.

Quebec City-based biotechnology company Medicago Inc. worked closely with the British Pharmaceutical giant GlaxoSmithKline (GSK) to develop the innovative plant-based vaccine. The two companies worked together to develop a new production method that would avoid using an actual virus, eggs, or other animal-based ingredients to create the vaccine dose. The result is a fully vegan coronavirus vaccine created with proprietary plant-based protein technology.

What makes a vaccine plant-based?

To create the plant-based vaccine, Medicago uses live plants to produce virus-like particles that are manipulated to replicate the genetic structure of COVID-19. The plants act as bioreactors, removing the need to incorporate animal-based or live viruses during vaccine development. The revolutionary vaccine is a major victory for both plant-based Canadians and the Canadian biotech sector.

“As one of our government's top priorities has been to reverse the 40-year decline faced by Canada’s biomanufacturing sector, we are pleased to see Medicago’s vaccine approval,” Minister of Innovation, Science, and Industry Francois-Phillippe Champagne said. “It is a great milestone for Canada’s biotechnology sector and for homegrown innovation. We will continue to support companies that want to produce vaccines in Canada and join the growing national biomanufacturing sector.”

Is a plant-based vaccine just as effective?

With doubts about COVID-19 vaccines circulating now more than ever, people will be increasingly skeptical of new vaccines. In order to prepare for this doubt, GSK and Medicago conducted a study involving 24,000 adults across six countries to test the durability of the new vaccine. The study found that the plant-based vaccine is 71 percent effective against COVID-19 and 75.3 percent effective against the Delta variants.

“The approval of our COVID-19 vaccine is a significant milestone for Canada in the fight against the pandemic,” President and CEO at Medicago Takashi Nagao said.

Medicago’s plant-based vaccine is the product of nearly 20 years of technological development. The plant protein technology allows Medicago to accurately reproduce virus-like structures in order to reduce the need for live testing. The virus-like particles mimic the structure of real viruses, giving vaccine developers and scientists virtually identical genetic structures to work with. The company guarantees that the virus-like particles are then easily recognized by the immune system, ensuring its effectiveness.

Alongside the plant protein technology, Medicago will be using an immune-boosting chemical produced by GSK known as an adjacent. GSK’s adjuvant has been added to several other medicines in the past to improve the potency of vaccines. For Medicago’s new shot, the adjuvant will be added to the shots to help invigorate the immune system.

“This first approval is an important milestone in our approach of pairing GSK’s well-established pandemic adjuvant with promising antigens to develop protein-based, refrigerator-stable COVID-19 vaccines,” President of GSK Vaccines Roger Connor said.

The virus-like method also allows the COVIFENZ to be stored at normal refrigeration conditions (between 35.6º to 46.4º Fahrenheit), allowing for easy distribution across Canada. The two-shot dose has been cleared for adults between the ages of 18-64 years old, alongside a subsequent booster shot.

The 13 Best Foods to Boost Your Immune System to Fight Off COVID-19 Symptoms

Here are the best foods to eat on repeat, to boost immunity and fight inflammation. And stay off the red meat.

1. Citrus for Your Cells and Healing

Your body does not produce vitamin C, which means you need to get it daily to have enough to create healthy collagen (the building blocks for your skin and healing).The recommended daily amount to shoot for is 65 to 90 milligrams a day, which is the equivalent of one small glass of orange juice or eating a whole grapefruit. Almost all citrus fruits are high in vitamin C. With such a variety to choose from, it's easy to get your fill.

2. Red Peppers to Pump Up Skin and Boost Immunity with Twice the Amount of Vitamin C as an Orange Has

Want even more vitamin C, add red bell peppers to your salad or pasta sauce. One medium-sized red bell pepper contains 152 milligrams of vitamin C, or enough to fulfill your RDA. Peppers are also a great source of beta carotene, a precursor of vitamin A (retinol). How much beta carotene do you need a day: You should try to get 75 to 180 micrograms a day which is the equivalent of one medium bell pepper a day. But a red pepper has more than two and a half times your RDA for vitamin C so eat them all winter long.

3. Broccoli, But Eat It Nearly Raw, to get the Most Nutrients Out of It!

Broccoli may be the most super of superfoods on the planet. It's rich in vitamins A and C as well as E. The phytochemicals in it are great for arming and strengthening your immune system.How much lutein should you eat in a day: There is no RDA for lutein, but experts say get at least 6 milligrams.

4. Garlic, Eaten By the Clove

Garlic isn't just a great flavor-enhancer, it's essential for your health. Garlic’s immune-boosting properties are tied to its sulfur-containing compounds, such as allicin. Allicin is thought to improve your immune cells' ability to fight off colds and flu, and viruses of all kinds. (Smelling more garlic on the subway? It could be smart coronavirus management.) Garlic also has anti-microbial and anti-viral properties thought to fight off infections. How much should you eat in a day: The optimal amount of garlic to eat is more than most of us can fathom: Two to three cloves a day. While that may not be doable, realistically, some people take garlic supplements to get 300-mg dried garlic in a powdered tablet.

5. Ginger is a Power Player for Immunity and Digestion

Ginger is another ingredient that has super properties when it comes to fighting off illness. It has been shown to decrease inflammation, which can help if you get swollen glands or a sore throat or any inflammatory ailment. Gingerol, the main bioactive compound in ginger, is a relative of capsaicin, and is responsible for much of its medicinal properties. It has powerful anti-inflammatory and antioxidant benefits.How much should you eat a day: Most recommendations land on 3–4 grams of ginger extract a day, or up to four cups of ginger tea, but no more than 1 gram a day if you are pregnant. Some studies have linked high dosages to an increased risk of miscarriage.

6. Spinach, Wilted, Not Steamed (Also Kale and Dark Leafy Greens of All Kinds)

Spinach is not only packed with vitamin C but also antioxidants and beta carotene, both of which give your immune system the healthy boost it needs to fight off invaders. Don't overcook your spinach, since the more it's cooked the less active the antioxidants will be. If you eat it raw or lightly steamed you'll keep more of the nutrients intact.How much should you eat a day: Aim for 1 cup fresh spinach or 1/2 cup cooked per day, but this is the right moment to try the raw or slightly wilted approach. Order warm or wilted spinach salad when you go out, or make it yourself with olive oil, pine nuts, and vegan parm.

7. Almonds for the Win, Pop Them Like Candy

Vitamin E in almonds will help ward off colds and flu and is key to your immune system humming along. It’s a fat-soluble molecule, meaning it requires the presence of fat to be absorbed, so nuts are the perfect package for E to make it into your system.How much should you eat in a day: A half-cup serving, or 46 whole, shelled almonds, provides almost 100 percent of your RDA of vitamin E. Almonds are great for you but they don't come with a "free" pass, since 1/4 cup is a serving and has 162 calories, so double that for your RDA and you're eating about 325 calories. Throw them into smoothies instead.

8. Turmeric to Fight Inflammation, Put it In Your Tea or Smoothie

This highly pigmented spice is known for its anti-inflammatory qualities. How it helps immunity? It decreases exercise-induced muscle damage. Tumeric bolsters the immune system by stimulating antibody formation and people with auto-immune diseases are told by their doctors to take 500 mg of curcumin daily to reduce inflammation and stave off soreness.How much should you eat in a day: Try adding extra Tumeric to your diet during periods of stress or during flu season. Or take 500-2,000 mg of curcumin to help fight inflammation and power up your immune system.

9. Green Tea by the Gallon, Skip the Coffee and Sip this Instead

Green tea has high levels of EGCG, (epigallocatechin gallate) a hard-working antioxidant that is known to boost immune function. Green tea is steamed so the EGCG is still active when you drink it.Green tea also contains L-theanine, an anti-oxidant which appears to help in the production of T-cells in your body, the killer  L-theanine may aid in the production of germ-fighting compounds in your T-cells.How much green tea should you drink in a day: The optimal amount is three to five cups in a day, but most people won't get to that level. Any amount is better than nothing. Swap out a usual beverage daily for green tea could improve your health.

10. Papaya, The Tropical Healer to Keep You Vacation-Healthy All Year Round

Papaya delivers over twice your recommended daily amount of vitamin C in one fruit. It also contains an enzyme called papain that has anti-inflammatory effects -- and inflammation is one factor in most illnesses, so avoiding it can help your body fight off bacterial infections like sinusitis.Papayas contain potassium, vitamin B, and folate, which is a powerful cell rebuilder. Exactly how folic acid works to build immunity is linked to its role in protein synthesis, and researchers think that any mechanism in which cells proliferate can be affected (which is why it's critical for pregnant women). People who are folate-deficient have compromised immune systems.How much folate should you eat a day: Whether you are pregnant or not, folate (vitamin B9) is a great vitamin to keep your cells healthy and strong. The recommendation is 400 micrograms a day, or get it from legumes, spinach, papayas, and avocados.

11. Kiwis, a Vitamin Powerhouse

Kiwis are full of folate, vitamin K, vitamin C, and potassium. These vitamins in combination work in the body to build healthy cells, fight infection and keep your immune system humming along. Vitamin K deficiency is rare but when people don't have enough they suffer from weak bones and compromised immune systems. The inflammation system in the body is also dependent on vitamin K, especially your killer T cells that mobilize and fight cancer and other diseases.How much should you eat in a day: Vitamin K is one of the unsung heroes of the body. Women should get 90 micrograms a day, and men should have 120 micrograms.

12. Sunflower seeds to sprinkle on salads or eat by themselves

Sunflower seeds are especially healthy since they provide phosphorus, magnesium and vitamin B-6 as well as vitamin E. Your immune system needs vitamin E to function at full throttle. You can also get vitamin E from avocados and spinach and broccoli.How much should you eat in a day: Anywhere from 1 ounce (30 grams) per day to a healthy handful is considered healthy, but because they are high in sodium you might want to refrain from eating the entire bag. The raw seeds have 204 calories per quarter cup.

13. Miso, Soup or Paste to Add to Your Soups and Salad Dressings

The nutrients in miso -- which is a soybean paste that has been fermented with salt and a koji starter -- boosts immune system function by delivering healthy probiotics to the gut, making your microbiome healthier. How does Miso benefit your immune system?  It is a "sirt" food, which are foods that contain high levels of ‘sirtuins’ or proteins that regulate cells and activate metabolism. A diet high in sirts is believed to lead to weight loss, increased wellness and longevity.How much should you eat in a day? Researchers believe that consuming one bowl of miso soup per day, as is the tradition in Japan, lowers the risks of breast cancer. Other than its high sodium content there is no reason to stay away from miso with all its varied health benefits. We say cheers to that.
