Get a Licensed Technician
In order to get a flu shot at home, you will need someone who is authorised to give flu shots. There are many trained professionals who hold clinics for these shots in hospitals as well as pharmacies and people get their flu shots from these professionals. Engage them and get an appointment with such a person. You may need to drive them to your home as well. Make sure that there is no prohibition in your state when it comes to giving such medication at home.
Generally the price charged for a single shot by a technician including the medication is around twenty dollars. However, you can expect it to bump up several times as at-home services generally cost a lot more. Be prepared to spend some more and you can always discuss the rate that will be charged ahead of time. This can work in your favour and if you have numerous people who are getting a shot, it can help as well.
Once everything has been decided, get an appointment. Make sure that it is made for a time that everyone is available at home so that no one misses out. Also make sure that the kit that the technician brings to give the shots has brand new syringes and they are disposable. Make sure that all necessary precautions have been taken.
