Every car is a potential weapon, and many cars and vehicles of all types are, in fact, weapons.

So, it is a bioweapons lab?

Of course, not -- it's just a health lab that happens to produce bioweapons -- two totally different things.

We should ban all cars on streets because it is not safe?

Or alternatively ban all bio research including vaccine development because potentially they can be used as weapons?

Some are. But this is just another case of memetic warfare – weaponizing memes. :)
