一位朋友轉來一個東西，說65歲以上的可以選擇full dose 第三針或加強針

What is the difference between a third dose and a booster shot?

A booster dose is intended to offer a boost of immunity after original vaccination. This is recommended for everyone 18 and older because there is evidence that the effectiveness of the vaccine wanes over time.

A third dose is recommended for people who are immunocompromised and who received the Pfizer or Moderna vaccine series. This is recommended because there is evidence that this group doesn’t build up the same level of immunity after two doses of mRNA vaccine.

What you need to know about booster doses

Who is eligible for a booster dose?

The CDC recommends everyone 18 and older gets a booster shot.

• If you got the Pfizer or Moderna vaccine series, you should get your booster at least six months after your vaccine series.
• If you got the Johnson & Johnson vaccine, you should get your booster at least two months after your first dose.

Teens 16–17 years old may get a Pfizer COVID-19 vaccine booster.

Why are booster doses recommended?

Although the COVID-19 vaccines remain effective at reducing risk of severe disease, hospitalization and death, the CDC has found that their protection against mild to moderate disease decreases over time. Studies have shown that a booster shot not only lengthens immunity but helps to broaden and strengthen your immune response, even against variants such as omicron.

所有跟帖： 

• 我剛打完p第三針。打的特別快。我懷疑是half dose。有點遺憾沒確認一下。不是M才才half dose嗎？靜觀今晚明天的反應 -香草仙子- ♀ (0 bytes) () 12/20/2021 postreply 14:02:19

• 不會吧。P的隻有30微克的成人和10微克的兒童，沒有half dose的。五歲以下3微克還沒批呢。 -qiuqiu..- ♀ (0 bytes) () 12/20/2021 postreply 14:35:00
