Dr. Ashish Jha on how COVID-19 variants form – and what should happen

Although health workers around the world are administering the first batch of COVID-19 vaccines in hopes of ending the global pandemic, the increase in virus variants underscores the need for a faster-acting vaccine, says Dr. Ashish Jha.

Mutations formed new variants that originated in the United Kingdom, South Africa and Brazil. All were apparently found in the United States.

“There are variants when infections become wild, and selection pressure leads to dangerous mutations that can then thrive,” Jha, dean of the Brown University School of Public Health, wrote in A Twitter thread Thursday night.

“Each of these countries had major outbreaks even before their variants began,” he added in a subsequent tweet. ‘What are the implications if we ever want to end the pandemic? We need to bring (the) pandemic under control everywhere. ”

According to Jha, in order to crush virus outbreaks, officials need to implement virus control policies, expand testing, wear high-quality masks and “vaccinate the world as quickly as possible.”

Jha demanded that an effort be made to manufacture vaccines around the world to speed up the doses.

“In a future where (the) US is vaccinated but others are not, we may see (the) increase in variants that can infect, break out here and other vaccinated places – requiring us to update our vaccines and all of them again. inent, “he wrote. “This is the nightmare scenario of a never-ending pandemic.”
