“Get vaccinated. It’s the only way out of this pandemic,”

①接種しても他人に感染させる危険あり、②接種率が地域によってムラがある ③変異株が出現する可能性 ④抗体が長続きしない ⑤ ワクチンうった人は他人との接触機会が増える

よって、感染症が流行しなくなる集団免疫に達しない、と

ただ、メッセージは同じで、ワクチンをどんどんうて、というのは変わらない 

Given what is known about COVID-19 so far, “reaching herd immunity through vaccines alone is going to be rather unlikely”, he says. It’s time for more realistic expectations. The vaccine is “an absolutely astonishing development”, but it’s unlikely to completely halt the spread, so we need to think of how we can live with the virus, Flasche says. This isn’t as grim as it might sound. Even without herd immunity, the ability to vaccinate vulnerable people seems to be reducing hospitalizations and deaths from COVID-19. The disease might not disappear any time soon, but its prominence is likely to wane.

集団免疫を達しなくてもワクチン接種が人口に蔓延すれば、病弱者がコロナで入院したり死んだりする危険は低減することができる、と。

Herd Immunity: Will We Ever Get There? BY CARRIE MACMILLAN MAY 21, 2021 Vaccination is the key to protecting our most vulnerable. 

 Put simply, herd immunity means a large portion of a community is immune to a disease, making further disease spread unlikely. Immunity is conferred either by building antibodies after an infection from the virus or from a vaccine.

For Dr. Foxman, the take-home message when it comes to herd immunity is simple.

Get vaccinated. It’s the only way out of this pandemic,” says Dr. Foxman.

It’s likely, Dr. Foxman says, that instead of COVID-19 being eradicated, it becomes endemic, a term that describes when an infectious disease is constantly present in a population at a baseline, or predictable, level (much like the flu or common cold). 

Dr. Juthani says she believes herd immunity can be achieved, but that it may take several years. 

こちらでは集団免疫は可能だが何年もかかるという学者が登場しているが、いずれにせよ、結論は同じで、ワクチンどんどん接種してもらって、パンデミックからエンデミックへ、つまり、コロナが普通の風邪やインフルのようになっていく状態にもっていければいい、と。

コロナが絶滅できなくて、特定の地域で発生しても感染拡大の速度が緩やかで予想可能、制御可能ならそれでウイルスとの共存の目的は達成できるということではないか。
