San Francisco may be the first major US city. with herd immunity Expert Says | San Francisco



San Francisco may become the first major American city to be immune from the coronavirus. experts say

San Francisco still records a small number of coronavirus cases, about 13.7 per day, Dr George Rutherford. An epidemiology professor at the University of California, San Francisco, said they don’t seem to have a strong foothold in the population. causing widespread outbreaks

“That̵

Health officials are still lacking agreement on what percentage of the population must be immune to the coronavirus. What percentage to achieve status? The highly regarded “herd immunity” When so many people have antibodies against the virus that it can no longer spread to a wider community.

throughout the epidemic Herd immunity vaccination targets are moving targets. A Yale School of Medicine briefing recorded by experts initially estimated that the virus would be difficult to spread if 60-70% of the population were immune. with the flow of many strains which some species can spread more Estimates have increased Many experts estimate that herd immunity is attained when 80 to 90% of residents are vaccinated.

San Francisco is close to that goal. Nearly 80% of San Francisco residents eligible for the coronavirus vaccine have received at least one dose, according to the city’s health department, and 68% have been fully vaccinated. among the whole population Asians and Pacific Islanders have higher vaccination rates than the city average. while the black population had a delay rate of about 16 percent.

Dr. Peter Chin-Hong, UCSF Associate Dean, who specializes in infectious diseases. It’s believed that when you factor in who is immune to the coronavirus, San Francisco has residents with enough antibodies to immunize the herd. But he said the virus will never go away completely in the United States.

“I hope people are still out getting vaccinated and not resting on their laurels,” he said. “Virus will always be something we have to think about.”

San Francisco has several advantages in seeking herd immunity, Rutherford noted. Compared to the rest of the city, there are fewer children. This makes the population of the city more eligible for vaccination. The population is eager to comply with COVID safety measures and seek a vaccine. and has a compact geography It has a dense community packed into a 47-square-mile area that allows health workers teams to travel from home to home to cover and others who may have difficulty vaccinating.

“San Francisco has developed a national model for equitable distribution of vaccines,” Mary Ellen Carroll, director of the San Francisco Department of Emergency Management, said in a statement announcing the program. last month “Getting vaccinated door-to-door and delivering this lifesaving measure to returning home seniors and people with disabilities will help push San Francisco through our vaccine program.”

Chin-Hong noted that the city’s history of being at the forefront in the fight against the AIDS virus may build confidence in health measures that other regions lack.

“San Francisco has a long history of being open-minded and integrating academics and public health into community and politics,” he said. “Northern California is heavily promoting vaccines and wearing masks is popular. as well.”

A handful of counties across the country have higher full vaccination rates than San Francisco. This includes Hamilton County in New York, where 75% of residents are eligible for full vaccination, according to a data analysis maintained by the New York Times, but no county has a large city.

california which is preparing to reopen and lift restrictions on COVID-19 Most of them on June 15 were slightly behind San Francisco’s vaccination rate, with about 58% of the population getting one dose of the vaccine, according to statistics from Los Angeles. Times. The state has the highest vaccination rate in the country. But still behind 11 states, including Vermont, Massachusetts and Hawaii.

However, Chin-Hong said the fact California had the Covid-19 pandemic in the winter means the number of residents with immunity in the state is particularly high.

“California is like the US’s safehouse for COVID right now,” he said. It is one of the safest places.”
