I don’t usually contribute to GN discussions but I wanted to add my pennyworth here as this is such an important issue.
While it is important to ask questions, it’s also important to consult reputable sources of information about immunisation. This involves asking questions about the accuracy of the content of books and medical papers. Not all ‘medical journals’ are equally reputable.
Speldnan commented: “( until recent years Mercury was added to the vaccine but was proved to be dangerous and removed)”. Yes it is true that a mercury containing preservative Thiomersal (Thimerosal in the USA) was included in some vaccines. It was there to prevent bacterial contamination in the vaccine – to keep the vaccine sterile and safe. An important point is that this was never a constituent of MMR vaccine as it would kill the viruses. Thiomersal is no longer included in any of the UK routine vaccines and hasn’t been for some years now but not because it was “proved to be dangerous”, it was because it was because it was no longer necessary and it was removed as a precautionary measure. In any event the type of mercury used is ethylmercury, this is different from methylmercury which is known to be toxic in large amounts. Ethylmercury on the other hand, breaks down rapidly and is excreted from the body and does not build up. The issue about constituents is that they all have a role to keep vaccines as safe and effective as possible.
Quote from one review paper - Orenstein, W.A., Paulson, J.A., Brady, M.T., Cooper, L.Z. and Seib, K., 2013. Global vaccination recommendations and thimerosal. Pediatrics,131(1), pp.149-151.
“Overwhelmingly, the evidence collected over the past 15 years has failed to yield any evidence of significant harm, including serious neurodevelopmental disorders, from use of thimerosal in vaccines. Dozens of studies from countries around the world have supported the safety of thimerosal-containing vaccines. Specifically, the Institute of Medicine, and others have concluded that the evidence favors rejection of a link between thimerosal and autism.Careful studies of the risk of other serious neurodevelopmental disorders have failed to support a causal link with thimerosal.”

But the real issue is not that vaccines contain various additives, but the quantity of them. These additives are found in miniscule amounts. Anything in excess can be dangerous, even H2O. Some interesting reading here: www.senseaboutscience.org/pages/making-sense-of-chemical-stories.html
I am sorry that your grand daughter was unwell for a couple of days after MenB vaccine. It is well recognised that this vaccine when given with others can give rise to low grade fevers and in view of this, it is recommended that infant paracetamol is given as soon as possible after the vaccine. What you describe: irritability, hard lump etc are all recognised side effects of vaccines but clear up in a few days:
