الجواب وباللہ التوفیق
The following are some of the variants of the vaccine:
(1) If the vaccine contains halal ingredients, its use is strictly correct.
(2) In the present circumstances, if the ingredients are not known and the predominant assumption is that it contains only halal ingredients, then its use is correct.
Unless it is certain that the haram ingredients are mixed in it, it cannot be declared haram simply because of the suspicion of mixing the haram ingredients.
However, it is better to avoid it as a precaution.
(3) In a vaccine, if haram ingredients are mixed and a chemical transformation takes place, then its use is correct.
And the transformation of the essence means that the basic attributes, properties and effects of the haram thing on which the principle upon which Halal and Haram is based are eliminated automatically, or by chemical means, and if the scholars have researched and ordered the change of nature, then its use will be correct.
(4) It is not permissible to use the vaccine if the haram ingredients are mixed in it, but the final product is not completely transformed. However, if there is no alternative cure, without it, and the opinion of the medical experts is that the treatment is possible only by it, and there is no lawful alternative to it, in which case it will be allowed to be used as a matter of necessity. It should be well understood that use of vaccines is allowed only if there is a disease.
In case a person wants to get vaccinated before the disease, it
will not be permissible to use the vaccine if the mixture of haram ingredients is confirmed to have been included.
Note: Nowadays, the use of vaccines for travel is generally considered mandatory by the government, in which case the use of the vaccine is the same as mentioned above.
Moreover, if there is certainty or predominant suspicion of mixed haram ingredients in the vaccine, then it is allowed to use it only for the necessary travel, otherwise abstain from its use.
According to Fatawa Shami:
الْأَصْلُ فِي الْأَشْيَاءِ الْإِبَاحَةُ۔ (رد المحتار: ۶/۴۵۹)
فَإِنَّ الضَّرُورَاتِ تُبِيحُ الْمَحْظُورَاتِ (درر الحکام:۱/۴۰۴۔شامی:۳۵۳۲)
إذْ الضَّرُورَاتُ تَتَقَدَّرُ بِقَدْرِهَا(رد المحتار:۶/۳۷۰)
مطلب في التداوي بالمحرم: (قوله: اختلف في التداوي بالمحرم) ففي النهاية عن الذخيرة: يجوز إن علم فيه شفاء ولم يعلم دواء آخر. وفي الخانية
في معنى قوله عليه الصلاة والسلام: «إن الله لم يجعل شفاءكم فيما حرم عليكم»، كما رواه البخاري: أن ما فيه شفاء لا بأس به كما يحل الخمر للعطشان في الضرورة۔۔۔ (قوله: ولم يعلم دواء آخر) هذا المصرح به في عبارة النهاية كما مر وليس في عبارة الحاوي، إلا أنه يفاد من قوله: كما رخص إلخ؛ لأن حل الخمر والميتة حيث لم يوجد ما يقوم مقامه (رد المحتار:۱/۲۱۰)
ثُمَّ اعْلَمْ أَنَّ الْعِلَّةَ عِنْدَ مُحَمَّدٍ هِيَ التَّغَيُّرُ وَانْقِلَابُ الْحَقِيقَةِ وَأَنَّهُ يُفْتَى بِهِ لِلْبَلْوَى كَمَا عُلِمَ مِمَّا مَرَّ، وَمُقْتَضَاهُ عَدَمُ اخْتِصَاصِ ذَلِكَ الْحُكْمِ بِالصَّابُونِ، فَيَدْخُلُ فِيهِ كُلُّ مَا كَانَ فِيهِ تَغَيُّرٌ وَانْقِلَابُ حَقِيقَةٍ وَكَانَ فِيهِ بَلْوَى عَامَّةٌ،(رد المحتار:۱/۳۱۶)
فقط واللہ اعلم بالصواب
