Some of the most common mild side effects that can be seen after immunization include: Redness, mild swelling, and tenderness at the vaccination site Decreased activity levels (fatigue) Loss of appetite Low-grade fever. If any of these signs lasts more than 24 hours or if your pet appears extremely uncomfortable, notify your veterinarian. Nasal discharge, sneezing, coughing, or other respiratory symptoms, which may occur up to 2 to 4 days after an intranasal vaccine is administered. It is also common for a pet to develop a small, firm nodule at the vaccination site. It should begin to shrink and vanish within 14 days.

Vets vaccinate millions of pets each year and only a tiny number experience side effects, most of which are mild and pass within a few days. There are some common vaccine side effects that often only last a few days and disappear without treatment. If your pet is suffering mild side effects after a vaccination, monitor them and call your vet for advice if you are concerned, if their condition gets worse, or if their symptoms last for more than 24-48 hours. Common vaccine side effects include Low energy, Eating less, Sleeping more, Fever, and Mild swelling around the vaccine site that disappears in two - six weeks.
Less common side effects include Twitching, Itchy skin, Vomiting, Diarrhoea, and Limping. Vaccination is a very effective way of preventing disease and the benefits far outweigh the possible side effects. If you are concerned that your pet is at a higher risk of having a vaccine reaction, for example if they are old or unwell, discuss the risks with your vet to help you make an informed decision about whether to vaccinate or not.
In many cases, it’s wise to vaccinate vulnerable pets because they are at a higher risk of catching infectious disease.

These mild symptoms are normal and will likely only last a day or two. Most reactions associated with vaccines are short-lived and mild. Most dogs recover from these symptoms within a day or two. If your dog is still feeling lethargic after their shots or isn't feeling and acting back to normal within a couple of days, contact your vet. Yelping will usually stop in a few hours, or a day or two at the most. If your puppy is still yelping beyond the 48-hour timeframe, contact your vet. Anaphylaxis typically occurs very soon after the dog receives the injection but may occur up to 48 hours after the vaccine has been administered. Rear end paralysis - a condition most common in dogs that have had a Rabies shot - means that a dog's hind or back legs cease functioning as a result of a reaction, as unnerving as this sounds, the paralysis is not permanent and will probably improve on the tenth day after symptoms first appear.

Just as with humans, some mild problems may develop within a few hours of your pet receiving a shot, but these usually wear off after a day. These common discomforts include: Discomfort or swelling where the shot pricked the skin Low-grade fever Less interest in play, movement and/or food Runny nose, coughing and sneezing (usually 2-5 days after the vaccination). If these symptoms cause extreme discomfort or are still apparent two days after the vaccination, you should call your vet for a follow-up appointment. A small lump may develop under the skin at the site of the injection. It will most likely disappear within three weeks.

Dogs generally feel lethargic and uncomfortable after receiving their vaccinations, and their mild fever is frequently present as well. It should only take a day or two for these minor symptoms to pass. Contact your veterinarian if your dog doesn't feel better within a few days. Most dogs recover from these symptoms within a day or two. Anaphylaxis - This severe allergic reaction can involve facial swelling, diarrhea, itchiness, hives, vomiting, and breathing difficulties. This type of severe reaction will usually occur very soon after your pet receives the injection, (typically while you are still at the vet's office) but can happen up to 48 hours after the vaccine is given.

Anaphylaxis, a severe allergic reaction, usually occurs very soon after your pet receives the injection, but can happen up to 48 hours after the vaccine is given. Lumps and bumps are common reactions to dog vaccinations, just like feeling off, and these bumps form as a result of your dog's immune system rushing to resolve the localized irritation.
