Unlikely....the first shot even if it is mRNA is called the sensitization shot. The second shot is where the antibodies level are raised.
The key to Covid, whether one is already sick with other diseases or not, is Early Treatment. US Front-Line Covid-19 Critical Care Alliance, Dr. Darrell DeMello, Dr. Shankara Chetty, Dr. Vladimir Zelenko and many innovative doctors have put on Internet their successes.

For everyone...never take the Cold and Flu lightly. You need testing to determine whether it is Covid or not. Even though the PCR test is unreliable, it is better to be told you are positive than negative. Being positive means you are under monitoring closely and also self-isolation even without symptoms.
Covid is a dangerous disease after 7 days. So easy to dismiss the cough, sore throat, etc. as normal flu. But it suddenly gets vicious and starts to do downhill very quickly. For some. For many, we can survive and it depends on our immune response.
In late stage, the body mounts the deadly cytokine storm, a massive immune reaction. We do not die from
Covid "virus", we die from the massive reaction of our immune system.
