Synthetic mRNA lives a few hours out of the refrigerator. So using a heating pad, 3 times per day for about a week may be a good idea for obligatory mRNA vaccines. Vaccine mRNA exists in the deltoid muscles for a few days until is all absorbed into the cells. So we must use the thermal pad as soon as possible from the time of vaccination (not when the nurse can still see us).
Fever kills viruses so heating pads on the vaccine site may be also useful for vaccines with adenoviral vector.
There are also portable electric heating pads.
Some ultrasound machines for physiotherapy, transfer heat deep into tissue.
Pycnogenol is good for preventing thrombosis.
There are some studies showing that Stinging Nettle binds with the spike protein of SARS CoV 1.
