Covid booster shots can significantly reduce viral loads, a recent study in Israel revealed after analysing samples from 11,000 people infected with the Covid Delta variant.
Data shows that viral load in vaccinated people is much lower compared to the unvaccinated, which means even if they get the infection, the transmission will be minimal.
There are three key reasons which demand a booster dose. The first, if you didn’t respond adequately to the first two doses, second if you come under the category of immuno-compromised, and also when, over time, the immunity achieved as a result of the vaccine wanes off. We now know that the protection attained through vaccination starts to weaken with time. Depending on the type of vaccine, it can last anywhere from 7-12 months.
