"Recently, especially in the UK, the AY.4.2 strain of the Delta variant of COVID-19 has been discovered. There are about 45 subtypes of the Delta strain, one of which is the AY.4.2." Delta strain We see the same features in this mutation as in the other. Therefore, there is nothing to worry about, because Delta is a mutated version of COVID-19.

The statement came from director of the Scientific-Research Medical Prevention Institute Adil Allahverdiyev, APA reports.

He noted that as the virus mutates, so does its infectivity.

"COVID-19 is spreading 50 to 60 times faster than when it was first discovered. The new mutation is also spreading rapidly. However, there is no definitive information on whether the disease is severe or fatal. "After 5-6 months, the amount of antibodies against COVID-19 in the body may decrease. In order not to reduce the amount of antibodies, the 3rd dose of vaccine is given. In this case, it is advisable to inject the 3rd dose."

"When 60-70 percent of the population is vaccinated, our fight against the disease becomes easier. But there is a fact. We still repeat the vaccine every six months. If 60-70 percent of the population were vaccinated at the same time and everyone had antibodies to the virus, then the problem would decrease. "But it's not physically possible. Even if one group has antibodies, it may be low in others. But the disease can't be as widespread as it used to be, because most people have antibodies to the virus."
