DH had his 4th yesterday, Spikevax, headache last night, feeling general flu like symptoms today and spent day on sofa. Got mine Saturday, plus sheet from local pharma to fill in and book flu jab. A lot of people don't seem to realise these effects are your immune system doing its job. My eldest daughters good friend of over 30 years, contracted Covid March 2020,was intubated, remaining severely unwell,has been on TV with Kate Garroway,yet she herself had 2 jabs,no booster,no flu jab,is a healthy 52 year old,got Covid a few months ago, couldn't even get upstairs , said she wasn't having anymore.
