In an interview with the British BBC media, he says that vaccination has preserved the lives of millions worldwide. Burla says Pfizer vaccines were modified to create the best protection for new variants that David-19 has received for both Beta and Delta. Experts are trying to adapt it to create protection against Omitron, which is causing fear all over the globe and is believed to be the most contagious version ever circulated.
