New COVID booster recommendation for 12 to 15 year old adolescents

Yesterday the FDA authorized booster shots of the Pfizer-BioNTech coronavirus vaccine for 12- to 15-year-olds. The CDC’s Advisory Committee on Immunization Practices is scheduled to meet on Wednesday regarding the authorization. Based on previous experience we anticipate they will also approve administration of booster doses of Pfizer’s vaccine for 12 to 15 year old adolescents.

We are prepared to follow this recommendation, we have plenty of vaccine and appointments available. Please send us a MyChart message or call the office at 650.216.7794 to set up an appointment. Note: we anticipate a very high call volume so sending a MyChart message may be more efficient. We’ll keep you updated as this story develops.

PWG COVID vaccine update 10-26-21

Pfizer’s COVID vaccine is very close to getting emergency use authorization for children 5 to 11 years old, today the FDA’s advisory committee endorsed the vaccine. The CDC’s vaccine advisory committee meets next week to clarify recommendations, and once that occurs we anticipate the federal government to start releasing the vaccine the following week.
The vaccine formulation is different from what has been used for adults and teens – WE CANNOT USE THE CURRENT VACCINES FOR YOUNGER CHILDREN, we need to wait for the “new” vaccines to be delivered. The pediatric formulation is preservative free.
We’ve been administering the COVID vaccine to eligible patients in our practice since May of 2021, and we are actively planning strategies to get this vaccine distributed as quickly and as efficiently as we can to our younger patients once it gets approved.
What you need to know:
  • The fastest way to communicate with us will be through UCSF’s MyChart patient portal. If you are not signed up yet please go to and follow the instructions.
  • We have already placed our COVID vaccine pre-order with San Mateo County’s Health Department and it has been approved, we are waiting for a shipment date.
  • COVID vaccines will be shipped out in multiple phases, we should have enough COVID vaccine for everyone who wants it
  • we do not have any information on when the vaccine will be available for children younger than 5 years of age
This is an exciting time, we are proud to do our part to keep our patients, families and community safe. We will be posting more updates as information becomes available.

California is reopening today

It is official, effective today the California Department of Public Health (CDPH) announced the state will advance beyond the Blueprint for a Safer Economy, allowing businesses to return to normal operations with “common-sense risk reduction measures.” Individual counties are still allowed to enact local mandates, and the health care sector is still required to follow more stringent infection control guidelines. What does this mean for you?

  • Everyone over the age of 2 years is still required to wear a mask while in the office
  • We are no longer checking temperatures prior to entering our office
  • There can be more than 1 parent at a visit IF you have proof of complete COVID vaccination status. We will need to see your COVID vaccine card to confirm
  • You do not need to check in from your car, you can come into the office

It has been quite a year, and we are grateful to our families for their patience as we navigated all the nuances of this pandemic.  Team PWG implemented multiple safety measures as we remained open to serve our families and our community during this entire pandemic.  We know it is not “over”, but thanks to all your efforts we are in a much better place today.  Stay healthy, stay safe, and stay kind to one another as we enter this next phase.

The FDA approved Pfizer’s COVID-19 vaccine for adolescents 12 and up, and we are proud to have played a small part in vaccinating some of 600,000 US adolescents  that received this vaccine last week. There are also lots of updates about what is and is not recommended once you have gotten the vaccine. Here are some key items:

  • Summer camp can be a safe activity if they follow health and safety guidelines such as wearing masks, hand hygiene and physical distancing
  • The AAP has published a fantastic article about the science behind the COVID-19 vaccine, feel free to read and share
  • Your child is considered fully vaccinated 2 weeks after the second dose of the vaccine
  • Pfizer has announced plans to request EUA approval for COVID-19 vaccine for ages 2-11 in September
  • Experts still recommend that unvaccinated children 2 and up wear a mask when around people outside their immediate household

We have plenty of COVID-19 vaccine appointments so please call or send us a MyChart message to set up an appointment.  Team PWG wants to help make this a safe and happy summer for all our families!
