MYTH 4: The COVID-19 vaccines are not effective in preventing illness

All the vaccines are highly effective at preventing COVID-19.

It's important to note that an accurate comparison of all the vaccines is difficult to produce, as the Johnson & Johnson and Novavax trials occurred when variant strains of the virus had been introduced to the population. The Pfizer BioNTech (Pfizer) and Moderna Vaccine/Spikevax COVID-19 Vaccine (Spikevax) vaccines were tested before this was the case.

In clinical trials, the Pfizer vaccine was 95% effective against COVID-19, while the Spikevax vaccine was 94% effective. The Johnson & Johnson vaccine was 72% effective in tests conducted in the U.S. The Novavax vaccine was 90.4% effective in clinical trials.

All available vaccines perform exceptionally well in reducing severe cases, limiting hospitalization and death almost entirely. All available will save countless lives.

MYTH 5: I already had COVID-19, so I don’t need to get vaccinated

Evidence suggests natural immunity to COVID-19 may not last very long. Plus, you can still get re-infected with COVID-19 after recovering from it.

MYTH 6: The COVID-19 vaccines contain toxic ingredients

All COVID-19 vaccines contain common ingredients like fats, salts and a small amount of sugar.

In addition, mRNA vaccines contain Polyethylene Glycol (PEG), while the Johnson & Johnson vector vaccine contains polysorbate. The Novavax vaccine contains a purified protien of the virus mixed with an adjuvant. Learn more about the use of adjuvants in vaccines for decades. 

If you are allergic to PEG, you should not get an mRNA COVID-19 vaccine. Ask your doctor if you can get the Johnson & Johnson or Novavax vaccine.

If you are allergic to polysorbate, you should not get the Johnson & Johnson COVID-19 vaccine. Ask your doctor if you can get an mRNA COVID-19 vaccine.

Regardless of which vaccine you get, you should be asked if you are allergic to any of their ingredients.
