Sure.  When they are puppies, they should get quite a few shots 6 weeks apart.  When adults, once a year is recommended.  There is no harm in doing it more frequently, except to your wallet :)

Since your other question was about parvo absolutely do not vaccinate your dog right now since it seems your pup is already ill and you don’t want to vaccinate your pup just after them having the same vaccination. (  ) Had you recently done one before symptoms appeared? Was there a reason you did so other than a normal schedule or keeping your pup up to date? Who is giving the vaccinations, a vet?
If you had vaccinated shortly before the symptoms appeared it may be a severe reaction you are seeing or something else may have gone wrong. You should speak to your vet. Basically vaccination initially weakens the immune system so if your pup is ill, vaccinating and/or vaccinating again right now would not be a good idea, it is generally considered a very bad one.
They do get several sets typically and to remain up to date and protected against common and serious illnesses. As pups, due to fluctuating titer levels, their basic immune system and window of opportunity, vaccinations are typically given about  3 to 4 weeks apart until around 4 to 6 months of age depending.
Shortly after the puppy sets are done on schedule they are considered to be protected and okay for public exposure and higher risk situations and places. The vet will let you know when your pup can begin going out, it's usually a few days to a week or so after the last set of puppy shots and the immune system has a chance to stabilize.
The adult sets usually begin at one year. After that they are usually recommended yearly or a schedule is set up for vaccination and titer testing to monitor their levels of protection for those that prefer or need to run the testing to the potential of over or possible complications of vaccinating or whose dog’s situations are a little more complicated. You can speak to your vet about that if you'd like. A more common schedule with routine titer testing is three years for those vaccines but if you aren’t’ running titers regularly or it isn’t a financially feasible option, once a year is recommended.
You don't usually want to repeat vaccinations in short period of time or too close together. We also are careful not to vaccinate ill pets or ones that we have knowledge that may be particularly immune compromised at that time for some reason or often ones we are aware that have recently had a high exposure to a disease or illness.
Vaccinating has to do with the immune system and does have an effect. On it. Consider a situation where a puppy is vaccinated. For some reason the puppy is vaccinated again just a few days later and before the immune system has stabilized or has any protection. With the immune system unable to help or provide protection you may just be injecting the virus into their system and without protection may end up causing it.
Or you may wipe out the immune system just as your pup’s immune system is attempting to fight off a high rate of exposure giving the virus an opening to occur without an immune system to work to keep them from becoming actually sick.
If already ill, vaccinating would lower the immunity your pet’s body is using to try and fight the illness off and the result may be to allow the illness a bigger foothold, a much sicker pet, and a much more serious situation than if your pets immune system was in good working order and able to help fight off the illness.
The best thing to do is speak to your vet and they can help explain all of this if it’s needed or if you are requesting to vaccinate a pet who should not be vaccinated at the moment. These sorts of things are some of the reasons why you should not give any vaccines on your own without knowing what you are doing sufficiently and veterinarian supervision. I hope your pup is okay. Good Luck.
