“A booster jab will pump up your protection to 70-75% and it will also reduce your risk of a severe infection but that could also lend you a false sense of security. While it is important to get the unvaccinated vaccinated, first jabs would not be enough to fight off omicron. It takes many weeks for the immune system to develop a defense. The virus moves faster than that.”
