Highlights

  • In mid-January, WHO said there is no need for booster shots for healthy children and adolescents.
  • Boosters are essential for people with compromised immunity levels.
  • Several other studies have suggested that immunity from boosters may decline over time against emerging variants. 

With Israel leading the race of booster shots, several other countries are now focussing on booster shots of the COVID-19 vaccine. The pandemic that began almost two years ago has now showered the world population with multiple new variants. In order to protect world citizens from the deadly virus, the COVID-19 vaccine entered the rally.

Introduction to booster shots

The COVID-19 vaccine was made in order to provide protection against the virus. As new variants like the Omicron ventured, several countries embarked on a journey with booster shots. Some studies show that booster shots effectively provide prolonged protection against the virus. However, some studies suggest that multiple booster shots may not be the long-term and sustainable solution to fight the virus.

Decoding The Logic Behind Covid-19 Booster Jab

How does the vaccine work in the first place? - The vaccine has a dead virus in its solution. So, once the vaccine is injected, the body becomes immune to the virus. When it comes in contact with the virus from external sources, it is not adversely affected by it.

The vaccine makes the body immunised against the virus. Now, how did the booster shot come into the picture? - As the new variants like Omicron made an entry, it was realised that the human body needed prolonged immunity to fight new transmission. And several studies showcased that booster injections would enhance the body’s immunity against the virus. Thus, the idea of COVID-19 booster shots spread across.

Important things to know about the COVID-19 booster shots

It is significant to note that nothing is entirely black and white when it comes to booster shots. Countries like Israel and Germany are now moving ahead with the fourth booster shot, and children are also getting their boosters. However, in mid-January, WHO said there is no need for booster shots for healthy children and adolescents.

Additionally, boosters are essential for people with compromised immunity levels. However, people who are physically in good health with optimised immunity do not need the fourth booster shot.

Several other studies have suggested that immunity from boosters may decline overtime against new variants such as Omicron. Thus, making booster shots as the primary contingency plan against COVID-19 may not be sustainable for countries.

Conclusively, entirely depending upon booster shots to fight the pandemic may not be the best step. However, it is clear that boosters do provide higher immunity against the virus, thus, it is necessary to take boosters for people with immune deficiency.
