Additional Dose Of A Covid-19 Vaccine:
With the Omicron variant of Covid-19 spreading across the country, the need for a booster shot or an additional jab may feel more urgent than ever.
- An additional dose, originally called a third dose, is given to people with moderately or severely compromised immune systems to improve their response to the initial vaccine series.
- The term “third dose” was used to refer to additional doses for the two mRNA vaccines, but now the term is “additional dose” because those who received a Johnson & Johnson “one dose” vaccine may also be eligible for a dose based on their immune systems.
- People with weakened immune systems might not develop enough immunity after vaccination with two doses of a vaccine. An additional dose, thus, might improve their protection against the novel coronavirus.
- A booster shot is nothing but a means of strengthening one’s immune system against a particular pathogen. It may be exactly the same original vaccine, in which case its goal is to increase the magnitude of protection by producing more antibodies.
- The booster shot is an additional dose after the protection provided by the original shot(s) has started to decrease over time.
