Mumps can cause infertility. By giving a mumps vaccine to a boy, we are preventing the full effect of the disease if the boy has mumps in the future because the body is protected against this virus thanks to the vaccine.
Explanation:
Mumps can cause infertility in men. If we give a boy the mumps vaccine, we are giving him a modified version of the virus that is harmless, but that will make the body produce the specific antibodies for the disease. If in the future the boy has mumps it will be less harsh since his body has the antibodies to fight mumps and his fertility will not be at risk.
<span>There are a small number of boys who, after possibly contracting mumps, could experienced decreased fertility in the future. Giving a mumps vaccine, since it's a weaker version of the virus, will allow the body to fight it off without the negative effects that could come with a full version of the illness.</span>
if sex cells were identical, there won't be genetics variations and we will just all be identical to our parents. genetic variation allows us to better adapt and survive
