I need to know if the vaciene wil heal and prevent shingles in my face

Lots of help in this link. They told me I was borderline diabetic, so for the next test I didn't drink 3 cans of lager the night before and I drank a pint of water on the morning of the test. The result was perfect.

The purpose of the shot is to boost your own system to fight off shingles. The new shots are 2 separate shots. The first is followed by the second at least 8 weeks apart and no more than 6 months apart. This process provides greater then 90% protection by boosting your own immune system. Think of the second shot as a booster to the first one. Cost is about $280 for both, but often insurance will pay all or nearly all the cost as it is preventative.

This is a car forum, but let me help you with a google search finding:

If you had shingles in the past, you can get Shingrix to help prevent future occurrences of the disease. There is no specific length of time that you need to wait after having shingles before you can receive Shingrix, but generally you should make sure the shingles rash has gone away before getting vaccinated.

A Doctor or Dentist can prescribe antiviral medication which can be purchased from a pharmacy ("chemist"). Is your friend able to seek and obtain treatment?

Quoting from the internet link shown above:

"Start antiviral treatment as soon as possible. If you're diagnosed with shingles, more than likely your doctor or dentist will recommend immediate antiviral treatment (typically acyclovir or famciclovir) within 3 days of symptom onset. This can help speed up healing, alleviate pain and possibly prevent more serious complications."

Shingles purportedly follows nerves rather than spreading to different parts of the body by contact. Here are treatments according to the Mayo Clinic:

Keep the affected area clean, dry, and exposed to air as much as possible. Try not to scratch or burst the blisters. After the rash goes away, consider getting shingle shots to prevent or reduce subsequent recurrence.

The best treatment for shingles will be prescription antivirals. There isn't any over the counter remedies that help very much. Hydrocortisone may a little but not significant. Mostly you have to wait them out. Consider a shingles vaccine to prevent future outbreaks.

Hello Friend,
Here is a picture of shingles just to see if those itchy spots on your body can be shingles.
One of the distinguishing hallmark of shingles is that it has the pattern of following a line covered on your body by its accompanying spinal nerve. Oh shingles, how clever of you to have a pathway!
Now given the nature of vaccinations, I believe if people had any idea of what was being injecting into those immunizations they would be mortified, after all that is one way to build your immunity by injecting yourself with the very thing you're building defenses against. There are other healthier, safer ways to build your immunity. Case in point, I am a TRUE believer that if our immune systems were strong enough in the first place there would be no need for vaccinations.

Ash fault? I think you mean "asphalt" but that's OK. You haven't given enough information to solve the problem, but here's what you need to do.

You know the area of the roof is 300 square feet (sq ft). You should know the area of each asphalt shingle, although that's the information you didn't give. When you know that figure, the calculation is very simple:

number of shingles needed = area of roof / area of one shingle

I don't know if this is a class problem, or if you really have a roofing job. Don't forget that on a real roof, the shingles overlap. If you do the calculation, the number you get is right only if you lay the shingles edge-to-edge. A real-world roof would need probably twice that number. Shingles come packed in bundles, and they usually tell you the area they cover. (By the way, 100 square feet is termed a "square".)
