Understanding Vaccine Planning
Great care has been taken to ensure COVID-19 vaccines are safe and effective
Scientists had a head start. Although the vaccines were developed quickly, they were built upon years of work in developing vaccines for similar viruses.
Testing was thorough and successful. More than 70,000 people participated in clinical trials for two vaccines to see if they are safe and effective. To date, the vaccines are nearly 95% effective in preventing COVID-19 with no safety concerns.
There is no COVID-19 virus in the vaccine. The vaccine imitates the infection so that our bodies think a germ like the virus is attacking. This creates the antibody defenses we need to fight off COVID-19 if and when the real germ attacks.
No major side effects. Some people may have temporary reactions after being vaccinated, such as swelling from the injection, tiredness or feeling off for a day or two.
Those who need it most will get it first. A tested, safe and effective vaccine will be available to all who want it, but supplies will be limited at first. The best way to fight COVID-19 is to start first with vaccinations for those most at risk, then reach more people as the vaccine supply increases throughout 2021.
