Compared to Other Vaccines

The COVID-19 vaccines utilize a different approach compared to previous vaccines by injecting mRNA instead of a weakened form of the virus. But, this new mRNA approach has actually been researched by scientists for decades and has been successful in being implemented against the COVID-19 virus. Vaccines actually do not need such a high percentage of effectiveness to protect public health and diminish the pandemic—for example, the seasonal flu shot we receive is only 40-60% effective, according to the CDC. But, the flu shot is still extremely effective in preventing influenza illnesses and deaths.

It is important to note that no drug or vaccine is free from side effects; in fact, the COVID-19 vaccines have similar common side effects to the flu, measles, and polio vaccines.
