Why does gov. force preg. women&child to vaccinate? Maybe M&N's RSV&CMV vac. proj. will be the Ans.!

I'm sorry for no English subtitles...

I'm medical doctor in Seoul, South Korea.

M & N have RSV vac. project, it needs infant patients to trial.
And M has CMV vac. project, it needs preg. patients to trial.
Childs, infants, preg. women are the last unvaccinated groups.
The most recent vaccines may contain RSV and CMV vaccine sample.
