Many flu vaccines are actually grown in eggs. Whole "live" virus is injected into special chicken eggs. The eggs permit viral replication. The virus is then purified from the eggs and inactivated, further purified and then this is the vaccine. This is a pretty slow process, which is fine for annual flu vaccines, but not for this race against time siutation. The Pfizer and Moderna vaccines are mRNA vaccines which are essentially synthesized rather than grown. No eggs are involved.
I am not aware of any advanced COVID vaccine candidates being grown in eggs, but that doesn't mean there aren't some that use that technology. There are MANY vaccine candidates, and I've not followed them all.
Well this is good news for the people with egg aligiee
