Starting Monday, booster shots for anyone who received the two-dose regiment of the Pfizer vaccine are available to some Washoe County residents. Those who are 65 years and older, long-term care residents, or anyone 18 and older with underlying health conditions or a high-exposure occupation are eligible. But you must have gotten your second shot more than six months ago. The shots are being administered at the Reno-Sparks Livestock Events Center. Booster shots have not been approved for recipients of the Moderna or J&J vaccines.
