ファイザー製ワクチンが「接種1回だけでも」有効とされはじめたホントの理由

 

自民PT、ファイザー製「接種1回でも」　有効との調査結果受け

　米製薬大手ファイザーの新型コロナウイルス感染症のワクチンを巡り、1回の接種でも一定の効果があるとの海外の研究データが発表されたことを受け、国内でも接種の進め方を再検討すべきだとの声が出始めている。同社のワクチンは現在2回接種が前提となっているが、世界的な供給の逼迫（ひっぱく）を受け、22日の自民党プロジェクトチーム（PT）の会合では下村博文政調会長が「（接種回数の見直しは）政治的判断になるので自民党で検討していこう」と言及。供給次第で今後、見直し議論が強まる可能性もある。

　厚生労働省はファイザーのワクチンについて、海外での治験データに基づき「3週間間隔で2回」の接種が必要としている。一方、イスラエルのチームは18日付で、接種1回でも発症を85％減らす効果があるとの調査結果を英医学誌ランセット（電子版）に投稿。これを受け、河野太郎行政改革担当相が対応を見直す可能性に言及していた。



　自民党PTでは複数の議員が「供給量が限られる場合、広く1回ずつ打ったほうが公平ではないか」との意見を表明。終了後、PTの古川俊治事務局長は記者団に「（供給スケジュールが）見えないし遅れてきていることを見込んでの話だ」と述べた。PT幹部の一人は「しゃくし定規に『2回接種』で進めて、一部の人しか打てなければ政治的に失敗だ」と語った。

　厚労省は、接種の仕方を見直す場合は、ファイザーからの薬事承認変更の申請が必要とみている。厚労省幹部は今後の対応について「他国の様子も見ながら判断することになるだろう」としている。【横田愛】

Here’s why the second dose of COVID-19 vaccine may cause symptoms 

Posted: Feb 21, 2021 / 09:20 AM EST / Updated: Feb 21, 2021 / 09:22 AM EST

NASHVILLE, Tenn. (WATE) — Many people are having reactions to the second round of the COVID-19 vaccine. The WATE Six On Your Side team wanted to find out why. Who better to ask for answers than the researcher who helped invent it?

“Let me get rid of my Star Trek background,” Dr. Spyros Kalams, with Vanderbilt University, said via Zoom.

You might remember Dr. Kalams from his Star Trek Zoom backdrop. He’s a Trekkie. He’s also a leading researcher for the Moderna vaccine at one of the top hospitals in the country.

He knows the second shot can make you feel sick.

“That was apparent even from the trials when we had vaccinated a lot fewer people,” he recalled.

A group of medical students in their 20s also know that.

“Really the first day there weren’t any symptoms or anything like that. Overnight, though, I got relatively feverish, got some night sweats,” Jesse Woodall, a med student in Mississippi, said.

Woodall’s family lives in Knoxville. He got the vaccine along with fellow med students.

Fever, headache, and body aches have all been reported after the second dose. Dr. Kalams said these aren’t side effects; they are a response.

“This is because the first shot did such a good job priming your immune system so that your cells in your body see that what’s in that first shot,” Dr. Kalams explained.

He said the vaccine revs up the T cells and B cells in your body. T cells are helper cells that help the B cells make antibodies. They’re part of the immune response.

“They’re primed and ready to go, so now you give the second shot what is like a boost and so now those cells they start to multiply. They’re making what we call cytokines. They’re making proteins that help them get the signal and start churning out the antibodies,” he said.

He said young people would likely have more symptoms than older people because their immune systems are more active. Those symptoms were good news to one of Dr. Kalam’s trial participants.

“I believe it was after his second shot, he said that he had a headache, nausea, fever, and he said he nudged his wife and said ‘I am so happy because he thought I’m having an immune response to the vaccine,'” Dr. Kalams laughed.

He said the symptoms usually go away after about 24 hours. Not everyone will have them.

“Some of us got them a little bit stronger. Some of us didn’t get anything at all,” Woodall said of the med students.

If you do develop symptoms, Dr. Kalams suggested Tylenol or ibuprofen and rest. He also had one more recommendation.

“I don’t know about chicken soup. I suppose it wouldn’t hurt! Whatever makes you feel better,” he laughed.

Ultimately, it’s a matter of waiting it out. Both Woodall and Dr. Kalams said a day of discomfort is far better than the virus itself.

Dr. Kalams reiterated that the COVID-19 vaccine cannot give you the virus. The vaccine is not made of dead virus.

No one has died from the vaccine, but allergic reactions have happened. They are very rare.

These symptoms and responses can happen with both the Pfizer vaccine and Moderna. In future trials, Kalams hopes to learn if more symptoms correlates to stronger antibodies.

In the spirit of re-branding, if you don’t trust the scientist, trust the Trekkie.
