While in Russia they get sick with coronavirus after being vaccinated with their domestic drug called “Sputnik V”, in America, trials are being successfully carried out to develop a vaccine to prevent infection.
Pharmaceutical giant Pfizer and German biotech firm BioNTech announced on Monday November 9 that their coronavirus vaccine is more than 90% effective in preventing Covid-19 among those without a prior infection, according to US CNBC, calling it “ a great day for science and humanity. “
Scientists hope for a vaccine against the coronavirus that will be at least 75% effective, while American infectious disease specialist Anthony Fauci previously stated that a vaccine with 50% or 60% effectiveness would be acceptable enough.

It is noted that protection against infection occurs after 28 days from the date of vaccination, which, according to the protocol of scientists, should consist of two consecutive doses. However, the final percentage of vaccine efficacy may vary as safety data and additional data continue to be collected.

The results were based on the first interim efficacy analysis conducted by an external independent committee to monitor data from a phase 3 clinical trial. An independent panel of experts oversees clinical trials in the United States to ensure the safety of participants.
U.S. officials and scientists hope a vaccine to prevent Covid-19 will be ready in the first half of 2021 – 12-18 months after Chinese scientists first identified the coronavirus and mapped its genetic sequence.
This is a record time for a process that typically takes about ten years to create an effective and safe vaccine. It took over four years to develop the fastest mumps vaccine (mumps) and was licensed in 1967.
Earlier, “Telegraph” wrote that as of the morning of November 9, more than 8 and a half cases of coronavirus infection were recorded in Ukraine.
