SAN FRANCISCO (CBS SF/AP) -- The NBA has raised the level of urgency regarding getting booster shots against the coronavirus, telling players and coaches including the Golden State Warriors that it is no longer advisable to wait before receiving the additional dose.
The booster shots should be received "as soon as possible, particularly in light of the current coronavirus situation and increasing cases," the league told teams Friday in a memo, a copy of which was obtained by The Associated Press.
Golden State is off to a league-best 10-1 regular season start but went through some training drama when star Andrew Wiggins initially refused to be vaccinated. He finally relented and has played a key role, averaging 17.4 points and 4.3 rebounds a contest.
On Friday night, the Warriors will be taking on the Chicago Bulls, who will be without Nikola Vucevic because of the league's COVID protocol.
Earlier in the week, the NBA and the National Basketball Players Association said they were recommending the booster shots be received by those who are fully vaccinated, suggesting that it get done by Dec. 1 in most cases.
But with positivity rates rising in many areas of the country, and with the rate of COVID-19 community transmission in most NBA markets considered by the Centers for Disease Control and Prevention to be "high" or "substantial," the league and union felt the additional urgency is now warranted. The NBA has seen an increased positivity rate among vaccinated players, team staff and family members of late, which is consistent with the trends in many places around the nation.
At least eight players are known to currently be in the league's health and safety protocols, meaning they are believed to have tested positive for the virus. Another who had been in the protocols, Philadelphia's Tobias Harris, played Thursday night in his first game back since testing positive.
Harris missed six games and had been dealing with symptoms.
"I'm working my way back into it," Harris said.
Other NBA players currently known to be in the league's protocols include Philadelphia's Joel Embiid, Matisse Thybulle and Isaiah Joe, San Antonio teammates Jakob Poeltl and Jock Lansdale, Cleveland teammates Kevin Love and Lauri Markkanen.
People who are fully vaccinated are still strongly protected against hospitalization and death from COVID-19. But immunity against infection can wane over time, and the extra-contagious delta variant is spreading widely. The NBA — following the lead of U.S. health authorities — want to shore up protection in at-risk people who were vaccinated months ago.
The guidance from the league earlier in the week made clear that those who received the single-dose Johnson & Johnson vaccine more than two months ago should prioritize getting a Pfizer or Moderna booster quickly. Those who received the Pfizer or Moderna vaccine more than six months ago were also told earlier in the week to seek boosters.
About 97% of NBA players have been vaccinated against COVID-19, the league has said. The most notable holdout is Brooklyn's Kyrie Irving, a perennial All-Star who is not being allowed by the Nets to play until he gets vaccinated.
