Are vaccines 100% when it comes to illnesses. Such as MG and mereks

[shannon84]

I got two chickens yesterday that are vaccinated for those two diseases. Both diseases are on my property

No vaccination has ever been 100% effective on humans nor animals as far as I am aware.

There are some good looking resources on Google if you search the effectiveness of your vaccines, for some reason they will not allow me to view them from the UK though.

Just like with humans, vaccines can help prevent severe illness but not necessarily disease. If your birds due contract these diseases they are less likely to get seriously ill from them but as mentioned above you should do your research. I vaccinate my birds against Marek’s disease and then later when they’re older against Fowl Pox.

Hi. Do you have chance to know where I can get unvaccinated chickens? It’s so rare but I need it . Best Diana

If you hatch chicks from eggs or buy chicks from a backyard chicken keeper’s flock, they will not be vaccinated

^^^ No Vaccine is 100% at anything. Not at preventing infection, not at preventing spread, not even at preventing symptoms. Many vaccines are intended to mitigate/ameliorate severity. and in the case of a "disease" like AI or Fowlpox where multiple, but similar, virii are responsible - just as in the case of human flu vaccines - they innoculate birds against several strains and hope, knowing that it is functionally impossible to innoculate against every strain. These are called "bivalent" (two strain) or "trivalent" (three strain) or "quadrivalent" (four strain) vaccines.

I can't speak to vaccine availability outside the US, but here, you pay extra for vaccinated birds, the default is unvaccinated.

The hatcheries used to make vaccinations optional when you buy... is that not a thing anymore?

Vaccination has NOTHING to do with GMO.

Keep studying.

Also, very few things pass from hen to chick - Salmonella is the most obvious, because the bacteria that causes it lodges in the birds ovaries. Also, Mycoplasma, and some really rare stuff.

There is no Salmonella vaccine. There is one for MG in chickens, though in commercial focks, they simply destroy the infected birds and start over. A practice I am prepared to follow myself (as an NPIP participant, my birds are tested annually, and I've agreed in advance to do so in the case of an infected flock).

I bought my chickens from a major hatchery and they are not vaccinated for anything.
They are 6.5 years old and I do not have any illness or disease in my flock.
