Q. “ What is the ruling on taking medicines/treatment before the illness occurs, such as vaccinations (at-Tat`eem)? ”
A. “ There is no harm in taking medicines/treatment if he fears that an illness may occur, because of the presence of an epidemic (wabaa·); or because of other reasons, on account of which he fears that illness may occur. So there is no harm in taking a medicine to repel the ailment which he fears. This is because of the saying of the Prophet (sallallaahu `alaihi wa sallam) in the authentic hadeeth:
“Whoever takes seven dates of al-Madeenah in the early morning, then he will not be harmed by sorcery or poison.”
This is a case of repelling an affliction prior to its occurrence. So likewise if he fears an illness and takes a vaccination against the illness which is occurring in the land, or in any place: there is no harm in tha,t as a case of prevention: just as an illness that has occurred can be treated with the medicine for that illness.
However it is not permissible to wear amulets and charms to ward off illness, or the jinn, or the evil-eye, since the Prophet (sallallaahu `alaihi wa sallam) forbade that; and he -`alaihis-Salaatu was-Salaam- made clear that this is from lesser shirk, so it is obligatory to beware of that.”
[ Shaikh `Abdul-`Azeez ibn Baaz –rahimahullaah-: ‘Majmoo` Fataawaa wa Maqaalaat mutanawwi`ah’ (6/26-27).]

ANONYMISED COMMENT:
Are vaccinations allowed when they clearly have haram ingredients such as fetal dna, MRC-5, WI-39c pig, monkey cells etc?

wa’alaikumusSalaamwarahmatullaahiwabarakaatuhu
There are a few points here:
[1]:
As far as I know none of the scholars here have declared vaccines to be forbidden. Rather the opposite – we have fataawaa from the modern day scholars saying that vaccines are allowed and something good. You have the fatwa from Sh bin Baz quoted above. Also this is a fatwa from Sh Sa’d ash-Shathree (currently one of the senior scholars in Saudi):
“Among issues having to do with epidemics and contagious diseases is the ruling on vaccinations that are given in order to protect against these diseases. We say: vaccinations are of two types:
(i)Vaccinations the effects of which are known from experience to give protection against this disease by Allah’s leave. The ruling on these is that they come under the same ruling as medical treatment, as they are a type of medical treatment. That is because they are included in the words of the Prophet (blessings and peace of Allah be upon him): “Seek medical treatment.” So they come under the same rulings as medical treatment. Some fuqaha’ had a problem with the idea of vaccinations and said: The vaccination is a reduced level of sickness that is transferred to the body so that the body will be able to fight the real sickness (so that the body gets used to resisting sickness). They said: How can we allow introducing sickness into the body? But the more correct view is that there is nothing wrong with doing that; rather it is a righteous act because the introduction of harm in this case does not result in further harm; rather it serves a purpose which is to protect the one who receives this vaccination from severe illness. This indicates that there is nothing wrong with receiving this vaccination.”

About the specific issue that you mentioned, then there are two responses:
Firstly there are rulings from the scholars which explain that a tiny amount of an impermissible substance mixed with a medicine doesn’t change the overall ruling on the medicine. This is what Sh Uthaymeen for example said about alcohol:
“Q17. There are some medicines – homeopathy and otherwise – which have in them some content of alcohol, ranging from 1% to 3%. Those who take these medicines and treatments
are usually unaware of the presence of alcohol. Is it permissible to prescribe such medicines and to use it as treatment? Also is it allowed to sell it?
Answer: A small percentage of alcohol does not harm. If 3% of it does not cause intoxication, then there is no problem in using it. I have heard that there are many medicines which cannot be preserved for long time except by adding some alcohol to it. So there is no problem with it. But if the quantity is more, like 50% or 60% (or any ratio which would cause intoxication), then its use is not allowed.”

Also if the impure or impermissible substance has been significantly altered / chemically changed then it becomes permissible. This was explained by Ibn Taymiyyah:
Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) said:
“With regard to smoke from an impure substance or matter, (the ruling) is based on a principle which is that the impure substance, if it is transformed and becomes good like other good substances, it is pure, like what falls into the saltworks of blood, animals that die naturally (without being slaughtered properly) and pigs becomes pure salt like the rest of the salt.
There are two scholarly views concerning this type of transformation. One view is that it does not become pure, as is the view of al-Shaafa‘i and is also one of the two views of the madhhab of Maalik; it is also the well known view of the companions of Ahmad and is one of the two opinions narrated from him. The other view is that it does become pure. This is the view of Abu Haneefah and of Maalik according to one of the two opinions, and it is one of the two opinions narrated from Ahmad.
The view of the literalists and others is that it becomes pure, and this is the definitive correct view, because these transformed substances are not referred to in any text of prohibition, whether explicitly or implicitly. So they are not haraam and there is no reason for them to be haraam, and there is no justification to suggest that they are haraam. Rather the texts indicate that they are halaal because they are pure. They also come under the category that all are agreed is halaal.”
[Majmoo‘ al-Fataawa, 21/70, 71]
All this is assuming that vaccines do contain the like of the above ingredients, which would need to be checked.

Also as a general rule please be careful about whatever information you get on the internet or on social media. Always best to cross-check and if need be you can always ask your doctor.
