Will I get sick after COVID shot number 2? Getting ready for Cruising.

I'm getting my second COVID-19 vaccination shot and I'm a bit worried about getting sick. Some of my friends have told me that they got sick after their second shot so I recorded 3 days after getting the shot #2. CDC says Cruising will be able to continue in July 2021: https://cruiseradio.net/cdc-new-guidance-means-cruise-ships-could-sail-by-july/ Video from Cruise with Ben and David on the CDC update: https://www.youtube.com/watch?v=atNOU8IjJFc
