Weekly Roundup for July 22, 2022

Published: July 22, 2022

The COVID case rate has remained high in Sonoma County for the past two months. With the highly contagious BA.5 variant circulating in the United States, many people are now contracting the virus, including President Joe Biden. While we are not seeing the same kind of severe outcomes like hospitalizations and deaths that we experienced early in the pandemic, COVID continues to disrupt people’s lives.

As people travel and gather this summer, the best health guidance remains the same: wear a mask, especially in indoor public settings and around vulnerable individuals to prevent the spread of the virus and keep the community safe.

This week’s digest provides helpful and important updates on the following:

  1. Vaccine distribution milestones
  2. Update on a new COVID vaccine from Novavax
  3. The evolution of COVID variants
  4. Vaccine and testing availability
  5. Other county news items
  6. Emergency preparedness tips & resources

Vaccine Distribution Milestones

  • As of today, 1,119,223 doses have been administered to Sonoma County residents.
  • Residents fully vaccinated: 388,481 - equal to 78 percent of the county’s total population.
  • Residents partially vaccinated: 29,962 - equal to 6 percent of the county’s total population.
  • Residents who have received boosters: 249,368 - equal to 65.3 percent of the county’s eligible population.

Current Sonoma County metrics:

  • Our rate of new daily cases per 100,000 population is 30.2.
  • Our case rate for unvaccinated individuals is 54.7 per 100,000 compared with 28 for vaccinated residents.
  • Our overall testing positivity rate is 15 percent.
  • Our equity metric testing positivity rate is 17.5 percent.

CDC Endorses Novavax Vaccine

A Centers for Disease Control and Prevention panel on Tuesday recommended that a newly authorized vaccine from Novavax be used as an option for adults seeking immunization against the coronavirus.

The Novavax vaccine is expected to play a limited role in the immunization campaign, at least initially. Last week, the Food and Drug Administration authorized it as a primary immunization for adults, but has not yet considered it for a booster shot.

Novavax is hoping its shot will appeal to Americans who have so far declined to be vaccinated. Somewhere between 26 and 37 million adults in the United States have not yet received a coronavirus vaccine, according to CDC data.

But in the countries where it has been available for months, Novavax’s shot has yet to have a significant effect on vaccination rates. Novavax said in its presentation to the panel on Tuesday that just over 1 million doses of its vaccine had been administered worldwide through the end of June, only a tiny fraction compared to the reach of competing shots.

The Biden administration said last week that it would buy 3.2 million doses of Novavax’s two-shot vaccine, enough to fully vaccinate 1.6 million people in the United States.

The vaccine was found to be highly protective against infection and severe disease from the coronavirus in clinical trials, but those were conducted before the emergence of the Omicron variant, which has sharply reduced the effectiveness of other authorized vaccines in preventing infections.

Novavax’s vaccine works differently from the three Covid vaccines previously authorized in the United States. It provokes an immune response with nanoparticles made up of proteins from the surface of the coronavirus that causes Covid-19. Similar protein-based vaccines have been used globally for decades.

Variant Evolution Vexes Scientists

The rapid evolution of COVID subvariants presents a challenge to health officials: They must make far-reaching policy decisions based on little biological certainty of which viral variants will be dominant this fall or winter.

The Food and Drug Administration said at the end of June that it would update vaccines for a booster campaign in the fall targeting highly contagious Omicron subvariants.

In eight weeks, the subvariant known as BA.5 has gone from a blip in U.S. case counts to the dominant version of the virus in the country, now making up more than 75% of new cases. Perhaps the most transmissible subvariant yet, it is pushing up positive tests, hospitalizations and intensive care admissions across the country.

There is no evidence that BA.5 causes more severe disease, but the latest metrics certainly bust the myth that the virus will become milder as it evolves.

Omicron and its offshoots have dominated for about six months now, and whatever incarnation of the virus comes next is more likely to be tied to the Omicron family than to earlier versions.

The Omicron family tree has been growing faster since Omicron BA.1 was first detected in late November 2021. New federal estimates on Tuesday showed that BA.5 made up about 78% of new cases in the United States as of last week.

Local Hospitalizations and Deaths

There were 49 COVID-related hospitalizations in the county as of Monday. Five of those COVID patients were in the ICU.

There have been a total of 500 COVID-related deaths reported here since the start of the pandemic.

Other U.S. Developments

Daily U.S. cases are averaging 124,683 up 24 percent in two weeks, according to a New York Times database.

COVID deaths are up 33 percent in the past two weeks to 436 a day. The United States has recorded 1,021,349 COVID-19 deaths.
