According to NBC News, current coronavirus vaccines may become obsolete a year later due to mutations in the virus.
According to a new survey by The People's Vaccine Alliance, nearly 65% of epidemiologists, virologists, and infectious disease specialists surveyed think the interval between the vaccine's effectiveness is about nine months or even less.
Less than one in eight respondents said the new strains of the virus did not threaten the effectiveness of the vaccine, although a majority believed that most vaccines would become ineffective and that new or modified versions needed to be developed.
The survey showed that 88% of experts believe that constantly covering poor countries with a low-effective vaccine will also increase the incidence of resistant mutations.
It is noteworthy that with the emergence of more mutations in the virus, vaccine makers announced that they had begun to work on enhanced variants that would deal with new strains.
