The current vaccines, say Pfizer's, had 44,000 people in their clinical trial. None of them had delta or lambda variant then. Why should we take a vaccine not tested on current covid variants? Most of our early why still remains valid.
But we both are mask advocates and heavy VD (D3) takers. My wife started to take it 4 year ago, and I since last June. Our kid was forced to get vaccinated. My wife's 2 sisters are not vaccinated (one has some condition). Her brother got vaccinated.
