I just read that bees don't have lungs how do their respiratory system works??

Correct. Insects do not have lungs they breathe through spiracles (tiny openings) that can open and close, as well as having filters to keep dust and other external contaminants out. 

I Just Read That Bees Don't Have Lungs How Do Their Respiratory System Works??

The spiracles run across their abdomen connecting to tracheae  which is where oxygen exchange takes place (In mammals this happens in the blood), that then connect to tracheole. The air sacs expand and collapse so force the air in the spiracles and into the trachea and almost function in that they can reserve air in them so insects can conserve water.

Honey bees have 10 pairs of spiracles, 3 pairs on the thorax and 7 pairs on the abdomen. Bees can use and accelerate the passage of air in their bodies via their air sacs, contacting them and increasing their respiration rate.

This adaptive function of their respiratory system actually helps them to fly and the first few spiracles are used for air to exit while the others for air entering, they also have valves to prevent backflow. This also allows the bee to cool down or heat up if it needs to, which is why you’ll see bees abdomens wiggling while they’re resting. They’re forcing air in and out of their bodies in order to rapidly cool down or heat up, which is important for flight.

Vaccine Infographic By Leon Farrant.

Vaccine Infographic by Leon Farrant.

I often speak with patients who tell me that they do not wish to be vaccinated because they do not see the point, that it is a farce, that it can cause autism (it does not), despite educating and informing them of the reasons behind it. 

In the same way that people who did not grow up during the great wars of the mid-twentieth century have little frame of reference as to what the toll of total war can be, neither can a newer generation of people who have never seen the effects of polio, smallpox, and measles ravage humanity. For many people in the developed world, these are just distant, faded memories captured in the pages of medical textbooks. 

I sincerely hope that the understanding of why we vaccinate does not become lost over time, that people need not fall victim to these preventable diseases; otherwise, the suffering, the challenges, and the research that went into developing these vaccines were all for nothing.
