Dr. Santora Explains Boosters Versus Third Doses    

There have been continued questions in the community about the difference between third doses and boosters in the context of COVID-19 vaccines. Our Deputy Public Health Officer Dr. Lisa Santora provides some clarity to those who are unclear about the differences between the two. 






What Can You Do to Prevent the Spread of Vaccine Misinformation? 

The first Emergency Use Authorization for COVID-19 vaccine was given in December of last year. Since that time, there has been conflicting information about the risks and benefits of COVID-19 vaccines. How do you separate truth from misinformation?  

Here are some tried and true recommendations to make sure you stay informed with the right information: 

  • Check the source – Look at what is being said. Is it “just the facts” or is it biased? Trusted sources rely on sharing science-driven data, not emotionally charged rhetoric. 
  • Check the date – This virus was first identified in late 2019. Since that time, our knowledge base of the virus has increased and changed as the breadth of science-based knowledge has increased. Something that was published in the early days of the pandemic may no longer be accurate. 
  • Check the data and the motive – Is the information ‘clickbait’ or is it supported by science?

What’s the Fuss About Variants 

Delta’s rate of transmission, or R0, is the reason behind the dramatic increase in the prevalence of the Delta variant since it was first it was first identified in December 2020. The rate of transmission for the original strain of COVID-19 was between 2 – 3 and it is between 5 – 9 for Delta. What this means is a person infected with the original strain would infect an average of 2 or 3 people and each person infected with the Delta variant is likely to infect between 5 to 9 people. 

What does this mean for Marin County? The most recent prevalence of variants of Sars-CoV-2 data in Marin shows the Delta variant makes up 100% of the specimens sent to the lab for sequencing. Nationally, the combined proportion of cases attributed to Delta is currently estimated to be greater than 99%.
