San Diego County's remaining vaccination super stations are getting ready to close.
Sharp HealthCare officials said Monday the Grossmont Center site in La Mesa will close this Friday, the Cal State San Marcos site will end operations on June 23 and the South Bay site at an old Sears in Chula Vista will stop administering doses permanently on June 27.
Any second-dose appointments after those dates will have to rescheduled, with some appointments moving to nearby Sharp facilities.
Scripps Health officials said Monday the super station at the Del Mar Fairgrounds will also be closing on June 30.
"Which represents the completion of our original commitment," said Scripps Chief Medical Officer Dr. Ghazala Sharieff about the site which first opened in February.

The super stations were designed to vaccinate thousands of San Diegans per day, but with more than 75% of county residents ages 12 and over now having gotten at least their first dose, demand has significantly dropped. More than 2.1 million San Diegans have now been vaccinated.
San Diego County health officials had said the super stations would be closing soon as they make a big push this month with mobile vaccination sites, adding that the distribution for vaccines will begin to mirror the rollout for flu shots. The Petco Park super station operated by UC San Diego Health closed earlier in March to make way for Padres baseball, while another site on the UCSD campus closed at the beginning of June.
Sharp has administered more than 500,000 doses at it's community clinics. Sharp officials also added their Coronado Community Center location will be closed starting Wednesday.
It remains unclear if or when COVID-19 booster shots will be recommended, but the state's top doctor said California will be ready to provide them to the masses if or when that time comes.
"All (COVID-19 vaccines) are being evaluated over their long-term usability and protective nature to determine when we might need to provide boosters," said Health and Human Services Secretary Dr. Mark Ghaly on Friday. "I don't think there's a clear answer yet for any population."
Ghaly added that the vaccines are protecting against new variants being discovered. Experts have suggested boosters may be required by the Winter of this year, but that they may only be for seniors or other vulnerable populations.
There other county-sponsored sites still delivering vaccinations and many pharmacy chains are continuing their efforts.
