All vaccines try to make the immune system that the pet has those vaccines - thus 'flu like' aches and pains are common. With that said, leptospirosis vaccine has a higher rate of vaccine reactions which is one of a couple of reasons that some vets chose not to give it.
Also many vets are no longer using corona vaccine as it is no longer recommended by AAHA in their 2006 guidelines. It may have some importance in high volume breeding and rescue site or areas that have a high prevalence of corona - however these are not typical scenarios. With that said, I do still see it commonly but if your pet is getting sore and uncomfortable - perhaps talk to your vet about leaving that one out.
