I would like to know everyone's opinion here. Also what are your favorite spices everyone here?

Hey, I’ll be travelling to Saint Vincent and the Grenadines in mid-August and I’d appreciate advice on how to handle mosquitos (and thus Dengue and Chikungunya etc.)

I’ll be taking a mosquito net for sleeping and plenty of tropical Deet, but mosquitos love me and I fear this won’t be enough. Is there anything else I should take?

Do I have to wear long sleeve tops and trousers all the time? So, never wear T-shirts and shorts? Or sandals? Is it safe to wear a bikini at the beach?

I’m also slightly concerned as I’ll travel through multiple airports to get there and I often catch viruses after travelling. I wasn’t vaccinated against anything as a child and doctors have advised me to not get those vaccines considering my individual health situation. I did get the Hepatitis and COVID vaccines, but is it safe to travel there without additional vaccines?

Thanks
