All You Need to Know About COVID Booster Shots

Over time, even COVID-19 vaccines may not be effective. Hence, many countries like the United States consider booster shots to lessen the spread of Coronavirus and its variants. The FDA officials declared that Americans vaccinated with Pfizer-BioNTech or Moderna-NIAID may get their booster shots this month as Delta variant cases have been rising. Before you get a COVID booster shot, discover everything about booster shots and how it works.

What Is a Booster Shot?

A COVID-19 booster shot is an additional dose made to maximize the protection as the protecting effect of original doses may weaken over time. Typically, people need booster shots after receiving original doses, particularly when the effectiveness is naturally beginning to wane. Booster shots are mainly produced to help people manage their immunity level for longer. It is the same as COVID-19 vaccines. It will mobilize immune system defenses so that it can protect against COVID-19 and its variants-Delta virus. According to Pfizer and partner BioNTech, booster shots can be given to people after six months of the second vaccine.

Why Might Booster Shots Be Needed?

The vaccination may lessen over time because our body’s antibody levels decrease. In such cases, an additional booster can refill the antibody levels and increase the immune response. For that reason, booster shots are mostly recommended. The CDC found that COVID-19 vaccines can protect against mild to moderate disease over time. 

Who Can Get a COVID-19 Vaccine Booster?

COVID-19 boosters will be given to people in the fall. Eight months after receiving their second dose of an mRNA vaccine (either Pfizer-BioNTech or Moderna), people can get their booster dose. FDA is ready to organize an independent evaluation to find the effectiveness and safety of a booster dose of the mRNA vaccine. 

Who Will Be the First People to Get a Booster Dose?

When the FDA and ACIP recommend a booster dose, people at more risk will first receive a booster dose. It includes healthcare providers, older adults, and residents of long-term care facilities.

What Is the Difference Between a Booster Shot and Third Dose?

The third dose of an mRNA vaccine is specially made for people immunocompromised. It is given around 28 days after the second dose. The third dose helps build the same level of immunity, just like the two doses. COVID-19 booster doses, on the other hand, are mainly made to provide a boost of immunity for a particular period after the original vaccination. Booster shots are another type of vaccine dose that is offered to individuals who already built ample protection after vaccination, but protection may decrease over time, also known as waning immunity. A study proves that the effectiveness of booster doses will wane over time. Hence, federal officials have been in a discussion to suggest booster shots eight months after the final dose of covid-19.
