This percentage of people need to be vaccinated for herd immunity

 


Geneva — World Health Organization scientists estimate that approximately 60-70% of people in the country need to be vaccinated against the coronavirus to achieve herd immunity of all kinds.

At a press conference on Friday, WHO vaccine expert Dr. Kate O’Brien said it is still unclear whether a vaccine against COVID-19 will reduce people’s infection time and ability to spread the virus. But she said modeling studies suggest that up to 70% of the population needs to be vaccinated in order for people to be protected from the disease.

O’Brien, head of the vaccination division of the United Nations Health Organization, said: Vaccines and biologics.

Dr. Michael Ryan, WHO’s head of emergency, said that in some situations, vaccination of specific groups could be more important than immunizing the entire population.

“In many clusters, we found that only 20% of cases infect others and 80% do not,” he said. “I think we need to be more accurate, more surgical and accurate about who will be vaccinated. It may be much more important to target specific sections of the community.”

COVID19 prevention

Most patients with COVID-19 present with mild to moderate symptoms. However, in a small proportion of patients, COVID-19 can lead to more serious illnesses, including death, especially among the elderly and those with chronic medical conditions.

COVID-19 spreads primarily through the respiratory droplets that occur when an infected person coughs or sneezes.

Symptoms include fever, cough, and difficulty breathing. Symptoms appear within 14 days of exposure to the infected person.

Virginia health officials have called for the following precautions:

  • Wash your hands frequently with soap and water for at least 20 seconds.
  • Use alcohol-based hand sanitizers only when soap and water are not available.
  • Do not touch your eyes, nose or mouth. If you cough or sneeze, cover your mouth and nose with tissue paper or sleeves (not your hands).
  • Cleans and disinfects frequently touched objects and surfaces.
  • Stay home when you are ill.
  • Avoid contact with sick people.
  • Avoid non-essential trips.
