Coronavirus News Update: How Optimistic Are You on Herd Immunity?

As a few countries in Asia and Latin America struggle to handle surges in cases, some epidemiologists believe the world needs to learn to live with the virus. It will always be a risk.

When Covid-19 first began to spread across the globe, experts believed we would achieve herd immunity through a lack of hosts that would stem the spread of the disease. However, a year on and places like India are being crushed with a frightening second wave.

Epidemiologists are worried that the virus is changing too rapidly with new variants that are more contagious. Combined with slow vaccination rates, herd immunity may not be achieved anytime soon.

The biggest fear is that Covid-19 will be an ever-present threat, known as endemic and here to stay, much like the flu virus.


However, on the West Coast, San Francisco is offering reasons to stay optimistic.

Case numbers have been kept low, they haven’t rushed to reopen like other cities, and San Francisco has a comparatively high vaccination rate within the U.S., with around two-thirds of all adults having received at least their first dose.

The city may be seeing signs of herd immunity. If the majority of people cannot catch and spread the virus, it will struggle to find new hosts, and infection rates will eventually diminish.

Herd immunity might be a far-off notion at a national level, but regionally the concept is being defined. With a population of over 870,000, San Francisco has only recorded 26 new Covid-19 cases on average per day over the past week.

Around 60-70 percent of all adults living in and around the greater metro area of San Francisco, with a population of 4.7 million, have already had at least one dose of the vaccine.

And it looks like the big-tech companies are making moves to reopen their offices. Salesforce has already opened dozens of offices but will reopen its San Francisco headquarters by the end of the month.

Experts estimate that 70 to 85 percent of a city’s population needs to be immune to reach herd immunity. A figure many people around the world are looking forward to reaching and a route to normality.

Whether you believe herd immunity is possible or not, there’s no denying that more vaccinations bring the hope of a time with no out-of-control community transmissions.
